There is actually a rainbow pokemon in pbb: it's a rainbow bidoof. It's texture is akin to a shiny pokemon card from the TGC, where a rainbow gradient is applied to the entire sprite.

However, Aku Aku Oddish do not share the same texture, therefore it is not a "rainbow" variant.

We've had several edit wars over this despite developer confirmation that it's a Crash reference.
